y' `My invention relates-'to the art of sampling to Fig.,6, showing therelative parts inangw TIES PATENT ollffrlcfaf i liquid, being moreparticularly a device or apparatus by means of which a true and accuratesample of the liquid Contents of a tank may be taken. y j

Petroleum oils, after production, arestored in large tanks of. manythousand barrels capacity and the contents thereof sold accord-V ing tothe gravity of the oil, so that it is extremely important to obtainuniform samples of the oil in the tank which will accuratelly disclosethe nature'ofthe whole body of oil in the tank, and it is4 one of theprincipal objectsof my invention to producea sampling device ofthecharacter described, by means of which a uniform sample of the oil inthe Y tank in a continuous vertical columnmay be taken.

i It is a further object of invention to provide means whereby asampling device of the character described may be readily assembledv andinstalled on any.v of the common forms of tanks now inuse for thestorage of oils and similar liquids.

Another object of my invention is to provide a devicey of the characterdescribed and vmeans of mounting the same on a tank wherefby thesampling device adjusts itself to a true vertical position in the tank.`v

Other objects and advantageswill appear Ahereinafter "fr0m` thefollowing v description n `and accompanying drawings. Y f

With respect to the vent openings 49, 49 and 50, such openings are outof register when the slots 46 and 48 in the tubes are in register I sothat when the sampler is allowed to s tand' open, that is, the slots46and 48 in register,

l there is no leakage of gas through the sampler.

This is of great importance as gas leakage increases fire hazard andconsequently should l be avoided. However, during the operation offilling the sampler some of the top slots which are above the liquidlevel function as. air outlets whilethe passages 49, 49' and 50 l admitair during the draining of the sample ter with the outlet pipe. rI`hisis done by openp ing the valve 32, since if the mentioned accumulationof oil in the pipe were permitted to mingle with the sample, a truesample would not be received.
